Electrical impulse divider module
with printed circuit interconnect
matrix

ABSTRACT

A DIVIDER CIRCUIT MODULE FOR AN ELECTRICAL IMPULSE TOTALIZER IS PROVIDED WITH AN INTERCONNECT MATRIX INCLUDING REMOVABLE PINS WHICH MAY BE REARRANGED TO CHANGE THE PARTICULAR DIVISION OPERATION OF THE MODULE. THE MODULE COMPRISES A FIRST SET OF CONDUCTING STRIPS ON ONE SIDE OF THE CIRCUIT BOARD, THE STRIPS OF THE FIRST SET BEING CONNECTED AT ONE END TO ONE OR MORE TERMINALS OF THE COMPONENTS AND HAVING UNCONNECTED TERMINAL LOCATIONS ARRANGED IN A MATRIX CONFIGURATION, AND A SECOND SET OF CONDUCTING STRIPS ON THE OTHER SIDE OF THE CIRCUIT BOARD, THE STRIPS OF THE SECOND SET HAVING UNCONNECTED TERMINAL LOCATIONS ARRANGED ADJACENT TO, BUT INSULATED FROM, CERTAIN OF THE TERMINAL LOCATIONS OF THE STRIPS OF THE FIRST SET. THE TERMINAL LOCATIONS OF THE STRIPS OF THE FIRST SET ARE DISPOSED AT A LOCATION DIRECTLY OPPOSITE THE TERMINAL LOCATIONS OF THE STRIPS OF THE SECOND SET AND AN APERTURE IS PROVIDED THROUGH THE CIRCUIT BOARD AND THROUGH THE DIRECTLY OPPOSITE SUCH TERMINAL LOCATIONS. CONDUCTIVE PINS EXTEND THROUGH THE APERTURES AND ARE SOLDERED ON EACH SIDE OF THE CIRCUIT BOARD TO THE TERMINAL LOCATIONS OF THE STRIPS OF THE FIRST SET AND SECOND SET, RESPECTIVELY, AS REMOVABLE INTERCONNECT MEMBERS WHICH MAY BE LOCATED TO CHANGE THE DIVISION OPERATION OF THE MODULE.

Farnswortll, York, Maine, assignor to General Electric Company Continuation of application Ser. No. 366,555, June 4, 1973. This application Aug. 23, 1974, Ser. No. 500,157 Int. Cl. HllSk 5/00 US. Cl. 317-101 R 2 Sheets Drawing. 9 Pages Specification A divider circuit module for an electrical impulse totalizer is provided with an interconnect matrix including removable pins which may be rearranged to change the particular division operation of the module. The module comprises a first set of conducting strips on one side of the circuit board, the strips of the first set being connected at one end to one or more terminals of the components and having unconnected terminal locations arranged in a matrix configuration, and a second set of conducting strips on the other side of the circuit board, the strips of the second set having unconnected terminal locations arranged adjacent to, but insulated from, certain of the terminal locations of the strips of the first set. The terminal locations of the strips of the first set are disposed at a location directly opposite the terminal locations of the strips of the second set and an aperture is provided through the circuit board and through the directly opposite such terminal locations. Conductive pins extend through the apertures and are soldered on each side of the circuit board to the terminal locations of the strips of the first set and second set, respectively, as removable interconnect members which may be relocated to change the division operation of the module.
